Give yourself streamlined control over your Alpha·Omega 500/900 amp with the Alpha·Omega Intelligent Footswitch from Darkglass. A single footswitch puts two control functions at your feet. A short single press will engage/disengage the αΩ engine. A three-second press mutes the amp.
Power is supplied from the amp via the 1/4" TS connecting cable; just plug a regular instrument cable from the footswitch to the footswitch jack on the back of the head, and you're good to go.
